Interesting. I bought 2 OrangeRx 9ch back in Jan. Using them on 2 quadcopters.

Both use mystery 20A's (hmmm, same as ZTW's). On a 4S battery 1-2 motors go nuts (noisy, unflyable) and on a 3S, they run fine, but eventually both cut motors at around 5-6min of flight, consistently. Upon a rearm after a crash they run fine til exhausting the battery... I logged my quad copter throttle input and it shows the Rx cutting out (for 3-4sec) then in when raising the throttle (e.g. looks like a square wave vs a nice ramp up).

I'll try the an independent BEC, after all, it's a 9ch Rx and it could need a more power than say, a 6ch, though I only have 5 channels in use. I'm leaning towards brown out as a buddy of mine has/bought the same Rx and his quad runs fine (but using m2mpower ESCs....
